Application filerl August 2 lhc invention relates to a flexible joint ccustrncti ,i and more particularly to theclass of universal pipe couplings or JOllllS.

l l orimary object of the invent-ion is the )ll of a coupling' or joint of his charwherein the male menber is in the of a hollow ball while the feniiale memhe form of a sectional socket corre pondin iy shaped to and adapted to rolily receive the male inei -ber, so that the oupl'ti n' or joint will be freely flexible and can turn so that one pipe section can be posed atinryingg angles toanotherpipe section when joined by the coupling or joint.

gllil' object of the invention is the provision of a coupling or joint of this characlier wh our the "formation thereof affords lilllTC'" l connection between pipe sections so that the same will be freely flexible at the point of the oint whereby one pipe section can lye swun singularly with respect to the the possibility of leakage at coupling 01? joint being of Han or in the joint, novel form so as to of the sepai' 1 id pa rlis. c2

A it aer object theinvention is the ision of a coup which is remely simple in constructhorougrhi reliable and efficient in its m o .iomljded. strong durable and inexpensive to manufacture and install.

her ects of the invention will be in part obvious and in part hereinafter pointed out.

The invention accordingly consists in the elements and combination of parts, the construction of which will be exemplified in the description following and the scope of the application of which will be indicated in the claims hereunto appended.

ball-shaped end "4'', andan oppositenipple end or pipe extension 8, which latter may be detachubly connected with apipe section (not shown) or integrally formedtherewith.

The ball-shaped end of the male member A is truncated at a point remote from the nipple or pipe extension 6 to provide a circular relatively large opening 9 and the circumferentially of this opening is .7 kened at tie'inncr periphery thereof as at 10, the cute periphery of said thickened 4c beingr'formed witha packing seat 11, which is annular and has engaged therein a pool-Ling ring lQ -Which is formed with a folded over 66.3813 overlying the thickened edge 10 of the opening 9, the "ball-shaped end of the said iniile member A beinpgfiled within the ball-shaped end 7 of the female member ll and the packing ring 12" contacts with the inner surface of saidball-shaped end 2' ofthe female member and is held en? ber 13 is truncated to provide an openingv tting; thein'ertion of the male aentrica ly of the opening in the s formed with an annular 'ecess, L roviding an. inner abutment within the ball-shaped end 7, mile the surface of recess is provided screw threads for the detachable e .goinent of an externally threaded retaining collar 16, with the said edge circurn- T58 entially of the opening; in the ball-shaped end 7, the collar 16, being adapted to retain and secure the ballenie ped end 5 of the male member A in the ball-shaped end"? of the female member B yet permitting free turningz movement of said end 5 within the end 7, whereby the nipple ends or pipe eXtenin said foo-ale member llan d the.

O a cotter pin When inserted through the degree relative to each other.

The collar 16, can be worked inwardly in the recess formed in the ed e circumferentially of the opening in the. ball-shaped section 7 to abutthe shoulder 14L and by the swing to variableangles and at a maximum 7 adjustment of this collar 16, a snug fit can be had between the ball-shaped ends 5 and 1 7 01" the male and female members respectivelv When interfitted Withv each other while the oaclrin rin 12 Will avoid an r b D 7 V possible leakage between the'said ends 5 and r 7 in their interfitted relation to each other.

The recessed edge circumferentially or" the opening in the ball-shaped section '7 of the 'female member 13 has formed therein a diagonally disposed hole or passage 17, While the external portion of the collar 16 1s li'ormedwlth a notch 18, EICJlPlZEOl to register with said opening or passage 17, so that opening or passage 17, will engage the notch 18 for the locking of the collar 16, against turning I movement within the ball-shaped section 7 of thefemale member B and thus male member igand the securing of the retaming collar 16, in its engaged positionin the female m mber il of joint construction.

It will be obvious that the coupling or jointpermits a maximumdegree of uni- I the coupling or versal tCtlODtllGiYGOff, so that the nipple ends I or pipe extensions (3 and 8 of the male and femalemembers can swing to variable angles with respect to each other.

The packing ring 12 is caused to efiect a tight closure between the male and female members A and B, so as to avoid leakage therebetween as the fluid pressure Within the coupling or joint Will act upon the folded edge 13, of said packing ring 12,,and

cause to firmly brace against the-inner 1 surface of the ball-shaped end 7 of the fe-- male member.

7 From the foregoing, it is though that the construction and manner of operation ofthe member or joint will be-clearly understood, and therefore a more extended e planation has been omitted.

'What is claimed is:

l. A universal joint of the cl aracter described comprisingmale and female members, each being formed with a ball-shaped 'endand a pipe extension, the ball-shaped end of the male member being fitted: Within the ball-shaped end of thefeinale member.

a retaining collar having I screw-threaded engagement with the interior of the ballshaned. end of the female member and hold ing the ball-shaped end of the male member titted therein, said ball-shaped end of the female member and the collar being formed with angular registering openings and adapted to receive a locking pin for securing the cellar engaged with the ball-shaped end of the temale'member;

a. universal oint ofthecharacter desrribed. comprising male and female mem- V SETS each being r"ormedjwith aball-shaped e and a pine extension, the ball-shaped end of the male member being fitted Within the ball-shaped end of the female member, a retainingcollarlying contiguous with said male member and having screw threaded engagement 'i vith the interior of theball; shzqaedendof the female member and holding the ball shaped end of the male meml'ier fitted therein, said ball-shaped end of the ie'nale member and the collar being formed with angular registering openings and iLClRDEGLl to receive a locking pin for securthe collar engaged with theball-shaped endotthe female member, said ball-shaped end of the inale'rnember being formed with an annular paelringring seat in' the outer surface thereof, an; a packing ring engaged in said seat and contacting 'Withjthe inter-' nal surface of i mean 'WILSON.

the ball-shaped end of the 7 female member and held in said seat thereby.
